Web给大家介绍一些常用的光照模型的shader实现方法。 ... 如果你建了一个unity的surface类型的shader,会发现可以直接指定它的光照模型类型。 ... 我们经常听到的一些光照模型,比如上面的Lambert,或者Blinn-Phong,都是前人所发明的一些比较规范的光照模型。 ... This sample in High-Level Shading Language is a method of determining the diffuse and specular light from a point light. The light structure, position in space of the surface, view direction vector and the normal of the surface are passed through. A Lighting structure is returned; The below also needs to clamp certain dot products to zero in the case of negative answers. Without that, light heading away from the camera is treated the same way as light heading towar…

WebThe problem with Phong, with regard to the reflection and view directions being greater than 90 degrees, can be solved by changing the computation. This modified model is called the Blinn-Phong specular model or just the Blinn specular model. It is no more physically correct than the Phong model. But it does tend to account for more than Phong.
